I had sex 3 almost 4 weeks ago, none since. i have irregular periods but i havent had one for two months. kind of normal but i have spontaneous intense cramps in my uterus. thats not normal. and ive noticed that my discharge smells like semen?

Hard to guess: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A home urine pregnancy test gives a reliable result by 3 weeks after sex (3 weeks after when conception might have occurred) or 1 week after missing a period. An unusual vaginal discharge should be evaluated by one's doctor (can call first).
